Iterative deepening depth-first search (IDDFS) is an algorithm that is an important part of an Uninformed search strategy just like BFS and DFS. We can define IDDFS as an algorithm of an amalgam of BFS and DFS searching techniques. In IDDFS, We have found certain limitations in BFS and DF...
The Iterative Deepening A* (IDA*) (R.E. Korf, Artificial Intelligence 27 (1985)) algorithm often reexpands too many nodes while solving certain combinatorial problems. Algorithm IDA*_CR (U.K. Sarkar, Artificial Intelligence 50 (1991)) attempted to remedy this drawback. These algorithms require...
It is known that breadth-first search requires too much space and depth-first search can use too much time and doesn't always find a cheapest path. A depth-first iterative-deepening algorithm is shown to be asymptotically optimal along all three dimensions for exponential tree searches. The ...

Use Iterative Deepening A* (IDA*) algorithm which follows the Depth-first search strategy. IDA* has two parts: The main loop, initializes the thresholds B and B′ first. If no solution is found the search is triggered again but with an updated B = B′ threshold. The recursive function th...

algorithm degrades to the classic DTW algorithm. However, as the users’ tolerance for false dismissals increases, the search technique becomes much faster. The surprising result is that, even a very small tolerance for false dismissals results in extremely large ...
